Hello olly
Windslammes and other similar devices will make a difference, but whether its good or bad depends on the outfit and how they are set up.
Not all outfits will benefit, and it is not easy to give simple foolproof instructions on how to find the right position and angle for them.
Trial and error is really the only method left open to you.
Unless you are towing for a large percentage of your driving, it is questionable if such a device will actually save you any money at all. The difference they make is not likely to be more than about 2mpg, and you can buy a lot of fuel for the cost of one of these devices.
You will save more by slowing down by a couple of mph.

Depends on the design but the original Wind slammer designed at Loughborough Uni works and works well.
My own experience is little or no noticeable effect under 50mph, slightly after this though the van appears to get very much lighter as the slammer starts to really do it's job and wind resistance falls.
I have on numerous occasions though the van had come off! the effect can be that dramatic!!
Dad toured Europe with one doing upward of 2000 miles at a visit, his opinion is much the same but also notes the much reduced effect of buffeting as trucks pass.

I can't help but think there is more science to this than meets the eye. If examining the effect in a wind tunnel adjustments could be made to gain geatest effect but you can visualise that the placement would need to be different on an estate to a saloon car or with a 'eurostar' front like Fleetwoods or a more upright stance like a Bailey. Probably as with others there is more to be gained from a light foot and sensible loading - be interested to see if the recent manufacturer reads the posting and replies!
I'm sure they make a difference if PROPERLY set up.
What i used to laugh at when they were popular before was the bloke who drove 100 miles or so towing the caravan to his site with his wind slammer saving him fuel.
THEN spent all week sight-seeing with the thing still on the car!
LOL

When we towed with he estate car I found that we squeezed a further 3/4 mpg from the car on the motorway towing with the roof box on. With this in mind I would also think that the windslammer would make a small improvement to mpg. As John L says though it will take a long to to recoup the cost with fuel savings. Maybe better to buy a roof box and gain the additional storage space!
